Background: The occurrence of low grade dysplasia (LGD) in Barrett oesophagus (BE) is known as a pre-cancerous state. Current recommendation in case of LGD is a close endoscopic surveillance every 6 to 12 month and continuous Proton pomp inhibitor (PPI) treatment. Endoscopic radiofrequency ablation (RFA) has been demonstrated as an efficient treatment to eradicate high grade dysplasia (HGD) and most of LGD and BE.

Main aim of this study: To demonstrate that the prevalence of patients with LGD 3 years after a RFA treatment is lower than in a surveillance group.

Disability to take PPI oral medication or follow the protocol surveillance schedule
